Bc2000 (for the BCF2000 & BCR2000)

Hi, I am new in this this forum and a new user of bcf-2000. I want to use my bcf-2000 with DasLight (version DVC3). For this the presets have to be reprogrammed to "CC" only. This works fine with the BCF. Both BCF manager and BC-Edit communicate with the BCF, however I cannot actively send and receive data, the functions in the drop-down menue are not active. With the very old BC-Edit it works (old PC with old Java). What an I doing wrong?
